Workerman Framework Revealed: Explore its powerful online game development features

Introduction:
With the rise of online games, online game development has become more and more popular. As an open source, high-performance network programming framework, the Workerman framework has powerful online game development functions and has been sought after by many developers. This article will reveal the internal mechanism of the Workerman framework and demonstrate its power in online game development through code examples.

1. Introduction to Workerman framework
Workerman is a high-performance event-driven asynchronous Socket framework based on PHP. It implements asynchronous IO by utilizing PHP's event extension. It can be used to build various high-performance network services, including WebSocket servers, TCP servers, UDP servers, etc.

2. Internal mechanism of Workerman framework

1. Event-driven
   Workerman adopts event-driven programming. The program runs in a non-blocking manner. When an event occurs It is processed only when it is processed, which greatly improves the processing efficiency of the program.

   // 创建一个TcpWorker对象，并监听指定的端口
   $tcpWorker = new Worker("tcp://0.0.0.0:1234");
   
   // 当客户端连接上来时，触发onConnect回调函数
   $tcpWorker->onConnect = function($connection) {
    echo "New connection established
   ";
   };
   
   // 当客户端发来数据时，触发onMessage回调函数
   $tcpWorker->onMessage = function($connection, $data) {
    echo "Received data: {$data}
   ";
   };
   
   // 当客户端断开连接时，触发onClose回调函数
   $tcpWorker->onClose = function($connection) {
    echo "Connection closed
   ";
   };
   
   // 运行worker
   Worker::runAll();

2. Process Management
   Workerman supports multi-process mode, which can make full use of the advantages of multi-core processors and improve the concurrent processing capabilities of the program. Each Worker object can run in an independent process and will not affect each other.

   // 创建一个Worker对象
   $worker = new Worker();
   
   // 设置启动的进程数为4
   $worker->count = 4;
   
   // 每个进程启动时都会触发onWorkerStart回调
   $worker->onWorkerStart = function($worker) {
    echo "Worker #{$worker->id} started
   ";
   };
   
   // 每个进程停止时都会触发onWorkerStop回调
   $worker->onWorkerStop = function($worker) {
    echo "Worker #{$worker->id} stopped
   ";
   };
   
   // 运行worker
   Worker::runAll();

3. Client and server communication
   Workerman can easily achieve communication between the server and the client. The server can actively send data to the client and can also receive data from the client.

   // 创建一个TcpWorker对象，并监听指定的端口
   $tcpWorker = new Worker("tcp://0.0.0.0:1234");
   
   // 当客户端连接上来时，触发onConnect回调函数
   $tcpWorker->onConnect = function($connection) {
    echo "New client connected
   ";
    // 向客户端发送数据
    $connection->send("Welcome to the server");
   };
   
   // 当客户端发来数据时，触发onMessage回调函数
   $tcpWorker->onMessage = function($connection, $data) {
    echo "Received data: {$data}
   ";
    // 向客户端发送数据
    $connection->send("Received data: {$data}");
   };
   
   // 当客户端断开连接时，触发onClose回调函数
   $tcpWorker->onClose = function($connection) {
    echo "Client disconnected
   ";
   };
   
   // 运行worker
   Worker::runAll();

3. Application of Workerman in Online Game Development
The high-performance, event-driven, and multi-process features of the Workerman framework make it an ideal choice for online game development. Below is a simple chat room example.

// 创建一个WebSocketWorker对象，并监听指定的端口
$wsWorker = new WebSocketWorker("websocket://0.0.0.0:5678");

// 当客户端连接上来时，触发onWebSocketConnect回调函数
$wsWorker->onWebSocketConnect = function($connection, $httpHeader) {
    echo "New client connected
";
    // 向客户端发送欢迎消息
    $connection->send("Welcome to the chat room");
};

// 当客户端发来消息时，触发onMessage回调函数
$wsWorker->onMessage = function($connection, $data) {
    echo "Received message: {$data}
";
    // 广播消息给所有客户端
    foreach($connection->worker->connections as $clientConnection) {
        $clientConnection->send($data);
    }
};

// 当客户端断开连接时，触发onClose回调函数
$wsWorker->onClose = function($connection) {
    echo "Client disconnected
";
};

// 运行worker
Worker::runAll();

Conclusion:
This article reveals the internal mechanism of the Workerman framework and its application in online game development. The Workerman framework has powerful network programming functions, which can greatly reduce the workload of developers and ensure the performance optimization of online games. I believe that through the introduction and sample code of this article, developers can better understand and use the Workerman framework and accelerate the development process of online games.
